Animate Legion

You send gathered necrotic energy cascading into the ground around you, and seconds later corpses within the area start to twitch and drag themselves to their feet. You choose a number of corpses within range equal to your spellcasting ability modifier and animate them, as if with the animate dead spell.
Treat these animated corpses as zombies, with the following exceptions. The zombies follow your commands to the best of their ability but are not intelligent and take things very literally. Each zombie's initiative is the same as yours, but its turn does not take place until yours ends.
